In the past 10 days, I've been injecting a non preservative water solution along with the hgh compound itself. I though early on in this test that it was going to improve my negative reactions, but that was just hopeul thinking. I have not improved althrough, I'm learning how to take it in low dosages with some results. I've noticed that I burn more calories for sure. Maybe as much as 20%! (dmjr)
